How will the CO2 be delivered to the storage area? Will it be in a gaseous state?
A pipeline will be used, most likely 10-16″ in diameter, to deliver the CO2 from the plant to the permanent storage area. (One of the Candidate Sites would not require a pipeline because the storage area is at the plant.) At the plant, the CO2 will be compressed into a dense liquid-like state known as a supercritical fluid, which is like a liquid, before being transported for injection into the ground. It will then be delivered to the target storage formation at a depth greater than 3,000 feet, where the formation pressure will allow it to remain in a supercritical form.
